Hurricane Polo rapidly intensified into an 'extremely dangerous' Category 5 hurricane in the eastern Pacific, with maximum sustained winds of about 165 mph and a minimum central pressure of 905 mb as of Tuesday night, Sep 22. The storm was located roughly 210 miles south of Zihuatanejo, Guerrero, drifting slowly northeast at just 1 mph, and was undergoing an eyewall replacement cycle. The Guardian reported the storm intensified from tropical storm to Category 5 in fewer than 24 hours, driven by unusually strong El Niño conditions in the Pacific. While Polo is not expected to make a direct landfall in Mexico, its size and record intensity make it one of the most powerful storms of the season, and coastal Guerrero and nearby areas face dangerous surf, rain and wind risk. The National Hurricane Center continued issuing advisories tracking its slow movement and eventual weakening.
